Concept explainers
To describe the population and the type of sampling method used in the survey. Also, explain whether the sample is likely to represent the population.

Answer to Problem 9E
Random sampling method is used
Population = residents in a town.
The sample is likely to represent the population.
Explanation of Solution
Given information :
Since, the writer ask random costumer about their favourite flavour of ice cream at different local ice cream shops. Therefore, the method of sampling is Random because every resident in a town has an equal chance of being selected in this survey.
The residents in a town represent the population of the survey because the writer wants to determine the most popular flavour of ice-cream among residents in a town.
The sample is likely to represent the population because random sampling method is the most reliable way to represent the population.
